There's nothing creative about taking a bog standard lion and shoving a shark tail up its ass. A proper design would streamline its body and features for water, instead of slapping a bunch of clashing, competing elements on it with zero thought to form and function. It's a little kid mentality of "I want a big strong cool stoic mon that does everything!" including being fucking fighting type for no reason.
Fire creatures don't fucking exist, so the closest connection would be a hot climate animal, like tigers and lions. But that's not a requirement, it just means that if it doesn't have that natural connnection, it needs to be more heavy-handed with the fire. Moreover, Arcanine is a hybrid of 2-3 extremely similar animals, not a fucking big cat + bird + fish with no attempt to streamline them. A proper hybrid is something like Gliscor, which incorporates elements of both its animals in every part of its design, instead of a literal fucking bat with a scorpion tail stapled on.
